"Professional team, punctual and efficient. After the Keelcrab treatment, our yacht immediately handled better in rough seas. The hull was spotless and we saw a 15% reduction in fuel consumption on our next passage to Corfu. Highly recommend Captain Jack for any serious yacht owner."

"Running a charter business means uptime is everything. Captain Jack cleaned our entire fleet overnight — no hauling out, no delays. Our clients noticed the difference immediately. The boats glide through water now. This service pays for itself in satisfied customers alone."
BRAVADO
50 feet Poland / Bartek (Charter Company)
"Sailed all the way from Cape Town and the hull was a mess. Was dreading the haul-out until a fellow cruiser mentioned Captain Jack. They came to our mooring in Preveza, did the job while we were having lunch. Unbelievable! Yacht feels brand new again."
WILDE CHERRY
50 feet South Africa Beneteau Oceanis / Chris
"We operate daily cruises around Kefalonia, so appearance and performance matter. The Keelcrab cleaning removed two seasons of buildup in under two hours. Guests commented on how smooth the ride felt. We'll be calling Captain Jack every season from now on."
My Yacht
Mochi Caliari 50ft Motor Yacht – Kefalonia
"As a twin operation with My Yacht, we need both vessels performing identically. Captain Jack delivered consistent, professional results on both boats. The crew was knowledgeable, the price fair, and the convenience unbeatable. No more dry docks for us!"
My Yacht Too
Mochi Caliari 50ft – Kefalonia
"Live aboard full-time in Preveza Marina. Was skeptical about in-water cleaning but the results speak for themselves. The Keelcrab tech is impressive — quiet, eco-friendly, and incredibly thorough. My Prestige hasn't run this smoothly since delivery day."
Move On
Prestige 550 Flybridge Motor Yacht (Preveza)
"Being a Sunseeker owner, I expect white-glove service. Captain Jack exceeded every expectation. They accommodated our tight schedule, worked around our guests, and delivered a flawless hull cleaning. The yacht's performance improvement was dramatic — faster cruising speed at lower RPMs."
